Abstract:
Objective:To investigate the characteristics of magnetic resonance imaging (MRI) of minimal deviation adenocarcinoma (MDA) of cervix, and improve the diagnostic accuracy of MDA.
Methods:The imaging data of eight cases of MDA was retrospectively collected, including tumor size, tumor location, tumor components, signal characteristics, enhancement characteristics and invasive extent.
Results:The maximum diameter of tumor was (4.36±1.46) cm. Six tumors were mixed solid and cystic and two were predominantly solid. Six were diffusion limited on diffusion-weighted imaging, and two were not diffusion limited. On multi-phase dynamic contrast-enhanced scan, the enhancement curve of solid components of the tumor showed a plateau-like pattern in three cases and a slow-rising pattern in five cases. Tumors were confined to the cervical canal in three cases, infiltrated to cervical stroma > 1/2 depth in seven cases, and ≤ 1/2 depth in one case. There were four cases of uterine invasion, four cases of vaginal fornix invasion, four cases of bilateral ovarian metastasis and one case of lymph node metastasis.
Conclusions:Patients suffering from large amount of vaginal discharge had cervical lesions on MRI showing polycystic and solid component enhancement should be alert to MDA. Deep-seated cervical biopsy and even conization is conducive to early diagnosis, treatment and improvement of prognosis.
